中文摘要： 经典的含水和非水微乳液体系得到了广泛的应用，但由于所用的溶剂具有较窄的液体稳定范围，甚至有的溶剂具有挥发性和毒性，限制了微乳液体系的应用。本项目拟在设计合成功能化离子液体的基础上，用离子液体同时取代微乳液中的所有组分，形成全部由离子液体构筑的微乳液体系。利用电导、表面张力、等温量热、动态光散射、小角x射线散射、低温电镜等方法研究微乳液体系的相行为、微观结构、物理化学性质，分析离子液体阳离子结构、阴离子类型、体系的温度等因素对微乳液微观结构和物理化学性质的影响规律。并利用红外光谱、拉曼光谱、核磁共振等方法研究微乳液组分之间的相互作用，探索全离子液体微乳液体系的微观结构与宏观性质的内在联系，同时寻求该类微乳液体系作为绿色合成介质在纳米材料合成等方面的应用。本项目研究成果不仅会大幅度拓宽微乳液体系的应用范围，同时将会发展成一类新的绿色反应介质，对离子液体微乳液体系的研究和应用具有重要的参考价值。

英文摘要： The traditional aqueous and nonaqueous microemulsions have been reveived widespread applications in many fields. The major disadvantage of the conventional microemulsions is the relatively narrow liquid temperature range and using toxic volatile organic solvents. This significantly restricts the applications of such microemulsions. In this project, different functional ionic liquids were synthesized. Microemulsions solely consisting of three different ionic liquids were prepared. The phase behavior, microstructure, physicochemical properties of this novel microemulsions were characterised by conductivity, surface tension,isothermal titration calorimetry, dynamic light scattering, small angle X-ray scattering and cryo-transmission electron microscope. Effect of the structure of ionic liquids cation,type of anion and temperature on the microstructure and physicochemical properties of microemulsions were analysed in detail. The interaction between components of this novel microemulsions were discussed with FTIR-Raman spectroscopy and NMR. The internal relation between macroscopic properties and microstructure of this novel microemulsions were proposed. In addition, this novel ionic liquid-based microemulsions was used as green media for material synthesis in order to explore the new applications. It is expected that the results of this project will broaden the application field of microemulsions, and will provide new information for the research and application of ionic liquid-based microemulsions. At the same time, this novel system will also act as a newly green media for synthesis.
